(5) ТРАНСПОРТНОЕ СРЕДСТВО ДЛЯ ТРЕЛЕВКИ ДЕРЕВЬЕВ(5) VEHICLE FOR TRILING TREES

II

Изобретение относитс к машинам (ДЛЯ бесчокерной трелевки деревьев и может быть использовано в лесной промышленности.The invention relates to machines (for chainless skidding of trees and can be used in the forest industry.

Известно транспортное средство дл трелевки деревьев, содержащее раму, щит, закрепленные на раме с возможностью поворота в продольной вертикальной плоскости передние и задние рычаги, несущие стрелу с клещевым захватом, и силовые цилиндры управлени стрелой 1 .A vehicle for hauling trees is known, comprising a frame, a shield mounted on the frame with the possibility of rotating in the longitudinal vertical plane the front and rear arms supporting the boom with a tong clamp, and the power cylinders for controlling the boom 1.

Недостатком указанного транспвртного средства вл етс то, что стрела имеет ограниченную зону действи .The disadvantage of this transport means is that the boom has a limited area of operation.

Цель изобретени - расширение эксплуатационных возможностей транспортного средства путем увеличени зоны действи стрелы.The purpose of the invention is to enhance the operational capabilities of the vehicle by increasing the range of the boom.

Дл этого оно снабжено закрепленными на раме дополнительными силовыми цилиндрами, при этом задние рычаги выполнены из двух шарнирно со члененных звеньев, одни из которыхTo do this, it is equipped with additional power cylinders mounted on the frame, while the rear levers are made of two pivotally from member links, one of which

соединены с указанными дополнитель ,ными силовыми цилиндрами.are connected with the specified additional power cylinders.

При этом, щит закреплен на свобод ных звень х задних рычагов.At the same time, the shield is fixed on the free links of the rear levers.

На фиг. 1 изображено транспортное средство дл трелевки, вид сбоку, в транспортном положении с пакетом трелюемых деревьев на фиг. 2 - то же, в рабочем положении при вз тии пачки деревьев на максимальном вылете стрелы;- на фиг. 3 то же, в рабочем положении при заборе пачки деревьев, лежащих ниже уровн земли.FIG. 1 shows a hauling vehicle, side view, in transport position with a package of trebled trees in FIG. 2 is the same in the working position when picking up packs of trees at the maximum reach of the boom; FIG. 3 the same, in the working position when picking up packs of trees lying below ground level.

Claims

The vehicle for skidding includes a self-propelled chassis 1, on the frame 2 of which the front lever 3 is pivotally fixed, the upper part of which is pivotally connected with O by arrow C. : lower about 7 and upper 8 interconnected by a hinge 9. Lower link 7 of the rear lever 6 has a drive in the form of a power cylinder 10, under the action of which link 7 can rotate in the vertical plane of the hinge 11. On the top Link 8 is installed shield 12, which is designed to protect technological equipment from the blows of trees. On boom A, a catch 13 is suspended to grip a pack or individual k trees. The operation of the machine is carried out as follows. When collecting a pack lying on the surface of the earth, at the maximum outreach of the boom (Fig. 2), the machine backs up to the end of the pack of trees 1A, the catch 13 opens and the boom C moves to the extreme position using the power cylinder 5, and the lower link 7 is rotated relative to the hinge 11 in a vertical plane by means of the ram cylinder 10, approaching a horizontal position. The position of the gripper 13 with respect to the grip of the pack of trees in height and distance from the rear axle of the vehicle is adjusted by tilting the lever 3 or by turning the lower link 7. Then the jaws of the gripper 13 are closed, gripping it. Next, the boom returns to the initial (transport) position of the power cylinders 5 and 10, raising the grip 13 and the front part of the whip over the ground. The unloading is done by opening the jaws of the gripper 13. When picking up packs of trees lying below ground level (FIG. 3), the machine pulls back to the groove in which there is a pack of trees. In order to collect the pack, the gripper 13 is opened, and the arrow i is lowered on the lever 3 and the upper link 8 under the action of the power cylinder. Since the hinge 9 of the upper 8 and lower 7 links is well below the connection point of the front lever 3 with the frame 2, the arrow j lowers the grip 13 below ground level. The tackle I is captured. Then, the power cylinder 5 returns to its original position, raises the package above ground level and brings it closer to shield 12. The machine is unloaded by opening the jaws of the gripper 13 The proposed design of the vehicle has improved operational qualities by increasing the range of action of the movable boom grasping and securing the selection of bundles of trees or whips that are below ground level. Installing the shield directly on the upper links of the rear supports not only protects the technological equipment of the machine from the blows of trebled trees, but also simplifies its design. The combination of these useful properties makes the vehicle skidding more efficient. The economic effect of its use in comparison with the known increases by .15-20%, Claim 1. A vehicle for hauling trees containing a frame, a shield mounted on the frame can be rotated in the longitudinal vertical plane of the front and rear arms that carry the boom a tick, and power boom control cylinders, characterized in that, in order to expand its operational capabilities by increasing the range of action of the boom, it is equipped with additional power chi mounted on the frame Lindrami, while the rear levers are made of articulated links, one of which is connected with the specified additional power cylinders.

2. Vehicle according to claim 1, characterized in that the shield is fixed on the free links of the rear levers. Sources of information taken into account in the examination 1. US Patent No. 3731827, cl. 214-1 7, 1973 (prototype).
